Perhaps the most-anticipated film of 2018 is Avengers: Infinity War. The Marvel Studios epic recently wrapped principal photography, with fans eagerly anticipating any sort of official sneak peeks from the film. While footage of the film has yet to be released to the public, fans can get an inkling of what was occurring behind the scenes, thanks to a new Instagram post.

Robert Downey Jr., who reprises his role as Tony Stark/Iron Man in the upcoming film, recently shared a new BTS photo of him and costar Josh Brolin. Brolin plays the film’s primary antagonist, mad titan Thanos. You can check out the photo below.

The photo doesn’t really reveal a lot about Infinity War, aside from the fact that it appears to be taken on some sort of green-screened rubble set. Both Brolin and Downey Jr. are wearing mo-cap technology, hinting that Tony Stark will be in his Iron Man suit during this particular meeting with the Mad Titan.

It’s safe to say that when the duo’s characters meet onscreen, the rapport will be nowhere near as friendly. Nevertheless, the BTS image is pretty awesome – and gives fans an inkling of how much fun the film’s massive cast had during filming.
